It's as the title states I'm looking for a fan with reverse air flow and no I do not want to just turn the fan around. The purpose of this is for looks and my computer always sits on the floor and it's very easy to see the top fans through the mesh and they don't look all that good with the labels and colored wires showing. As well I want to keep the top fans all exhaust for obvious reasons. Hope I explained it enough.

As far as I am aware no because of how the blades are designed they really only work effectively in one direction of airflow.
I've never seen a fan in my time at least that was reversed, but who knows I could be wrong.

I would rather believe and find god doesn't exist than to not believe and find that he does.

I have seen a few that installed "backwards" to what I was used to during my travels. Unfortunately, that's just a "For What it's Worth" comment, as I can't point you to any one specific brand / model which was the "culprit".

Only thing I can think of is to search for "intake" fans as opposed to "exhaust".
